[dpdk-dev] [PATCH] eal: fix build with Xen dom0 enabled

[Thomas Monjalon]

There is a new function in the EAL API for internal use.
It has neither a proper prefix nor a .map export:
libethdev.so: undefined reference to `is_xen_dom0_supported'

Fixes: 719dbebceb81 ("xen: allow determining DOM0 at runtime")
